The document discusses evidence-based medicine (EBM) and how it differs from research methodology. EBM involves integrating individual clinical expertise with the best available external clinical evidence from systematic research, as well as considering patients' preferences in making decisions about their care. Research methodology, on the other hand, refers to systematically investigating topics to increase knowledge. The document outlines the steps to practicing EBM, including asking answerable clinical questions and searching the medical literature for relevant evidence.

10. Steps of Practicing EBCP

11. How would you search for answers? Ask the audience Ask a friend Flip through a textbook Google it up! Search the literature

12. It depends on the question! How do I look like in the pictures in the newspapers? Friends & Audience Where to download the latest song? Google What is the blood supply to the femur? Textbook What are the effects of soft drinks on fracture healing? Journals

13. What’s wrong with textbooks? Excellent for the principles & basic knowledge Usually single authored chapters Likely biased, author’s opinion Not peer-reviewed Outdated (at least 4 years)  except the frequently updated online books (not PDF eBooks)

14. What’s wrong with googling?

15. What’s wrong with googling? Reliability & credibility of source Google Scholar is good

22. Before we move on, What are the differences between articles & books? Are all articles good? Are all journals good? How does an article look like?

23. How does an article look like?

24. Read the article titles  If relevant, read the abstract If you read the abstract & it’s relevant  get the full text

25. Journal Name, Volume, Issue, Pages Article Title Authors & Contact Info MeSH Terms Abstract When you search by keywords, you search in these areas

26. How does a full text article look like? Same information as abstract, PLUS Introduction Methods Results Discussion References

27. Where are articles stored? Articles are published in Journals Journals are published by Publishers Journals are indexed by Databases (e.g., MEDLINE, EMBASE) Instead of going to each publisher website & look for articles, you search for articles in a database There are many companies/websites that searches a database (e.g., Medline): PubMed, OVID

28. Database (e.g. MEDLINE) Journal of Medicine Journal of Medical Research Engineering Journal Business Journal Article 1 Article 1 Article 1 Article 1 Article 2 Article 2 Article 2 Article 2 Article 3 Article 3 Article 3 Article 3 Article 4 Article 4 Article 4 Article 4 Article 5 Article 5 Article 5 Article 5 Article 6 Article 6 Article 6 Article 6 Multiple Browsers (e.g., PubMed, OVID) Publisher: Springer Publisher: Mosby Publisher: ABC Publisher: XYZ
